New Delhi: Civil nuclear cooperation will be among the major issues of discussion at the Summit meeting between Prime Minister Manmohan Singh and his Japanese counterpart Yoshihiko Noda here on Wednesday during which the two sides will also look at ways to enhance trade.

Noda will arrive here on Tuesday on a three-day visit amid India's expectations of increased Foreign Direct Investments (FDI) from Japan across the board and possibility of an agreement on USD 10 billion currency swap.

"I think this will be a subject that will be discussed between the two Prime Ministers at the summit," Gautam Bambawale, Joint Secretary (East Asia) in the External AffairsMinistry, told reporters here when asked whether civil nuclear issue, which is under negotiation, would figure in the 6th annual Summit.

Making it clear that the proposed deal was not off in the wake of radiation scare in Fukushima due to tsunami in March, he said there have been some informal consultations between the two countries after that incident.

Prior to that there have been three formal rounds of negotiations, Bambawale said.

"I am quite sure that this is a subject which will be discussed between the two Prime Ministers. What is the outcome of the discussions, I won't be able to tell you. We can leave it to the two Prime Ministers," he said.

Syed Akbaruddin, the new spokesman of the External Affairs Ministry, said civil nuclear cooperation issue has been receiving high level attention.

The two Prime Ministers will also discuss regional issues, including the new developments in North Korea after the death of its leader Kim Jong-Il. The Indian side would like to listen to the Japanese perspective from Noda, who will be on his first visit to India as Prime Minister.
